Modern engineering demands an agile approach that moves beyond traditional, linear development cycles. Unified CAD modeling and simulation (MODSIM) eliminates silos between design (CAD) and analysis (CAE) by allowing teams to design and simulate simultaneously on a common data model. This continuous loop supports rapid design exploration, allowing engineers to run what-if studies quickly. In one study, MODSIM halved the simulation analysis time for a subsea frame, **cutting effort from 60 man-hours to just 30**.
